So a House Rule of the Heal spell a Clr 6th level spell does 500hp of healing, single target. How does this impact (or doesn’t) change Mass Heal.
Level: Clr 9, Healing 9
Range: Close (25 ft. + 5 ft./2 levels)
Targets: One or more creatures, no two of which can be more than 30 ft. apart
This spell functions like heal, except as noted above. The maximum number of hit points restored to each creature is 250.
It will do 500 also.
